Description of intervention(s) / exposure
Treatment: Devices - BAROnova™ TransPyloric Shuttle™ (TPS™)

Treatment: Devices: BAROnova™ TransPyloric Shuttle™ (TPS™)
Subjects will undergo an endoscopic procedure to deliver the TPS™ into the stomach. The TPS™ moves freely without any physical attachment or invasive anchoring to tissue to reduce gastric outflow.
